OIL-CUP.

.SPECIPI CATION forming part of Letters Patent No. 339,489, dated April6, 1886.

Application tiled November 24, 1885. Serial No. 183,864.

To all whom it may concern:

Be it known that I, FRANK Oscnn SLANK- ER, of Pomona, in the county ofLos Angeles and State of California, have invented a new and ImprovedOil-Cup, of which the following is a full, clear, and exact description.

My invention relates to oil-cups adapted to supply oil for lubricatingthe bearings of shafts and other moving parts of machinery, IO and hasfor its object to provide a simple, inexpensive, and effective device ofthis nature which will keep the oil free from dust and grit and deliverthe oil in measured quantities.

The invention consists in certain novel featu res of construction andcombinations of parts of the oil-cup, all as hereinafter fully setforth.

Reference is to be had to the accompanying drawings, forming part ofthis specification, 20 in which similar letters of reference indicatecorresponding parts in both the figures.

Figure l is a vertical sectional elevation of my improved oil-cup, shownclosed and as adjusted to a hearing, which, also, is shown in section;and Fig. 2 is a vertical sectional elevation of the oil-cup, showing itsoperation in ejecting the oil.

The body portion A of the oil-cup has a screw-neck, B, at its lower end,by which it may be attached to a bearing, G, as shown in Fig. 1. The topof the cup is closed by a cap, D, which, preferably, is made to screwinto the body of the cup, and is apertured centrally to provide abearing for the spindle E, which has at its lower extremity a plugvalve,F, which is connected to the end of the spindle by a stem, f, ashoulder, 6, thus being formed on the spindle next the stem.

The lower end of the neck B is formed with a recess, b, which provides aseat for the valve F, and an aperture, 12, leads from the recess b tothe oil-chamber G, which is formed in the neck B immediately under theshoulder e of the spindle E. A spring, H, placed on 45 the spindlebetween a pin, h, in the spindle and the bottom of the body A of theoil-cup, acts normally to lift the spindle and hold the valve 13 to itsseat to prevent escape of oil from the cup.

When the spindle E is pressed downward (No model.)

by the finger and against the tension of the spring H from the positionshown in Fig. 1 to that shown in Fig. 2, the plug-valve F will belowered to open the outlet Z2, and thespindie-shoulder 'e willsimultaneously enter the oil-chamber G and eject all the oil which hadfilled into the chamber from the aperture b onto the shaft or movingpart fitted in the bearing 0. \Vhen the spindle is released, the springH will instantly force it upward and close the valve F and cut off theflow of oil from the chamber G until the next time the spindle isdepressed. The shoulder a of the spindle, when raised, stands aboutlevel with the top of the oilchamber G, allowing the oil to flow past itto fill the chamber, and instantly cutting off the flow to the chamberfrom the body of the cup as the spindle begins its downward movement;hence the size of the oilchamber G governs the quantity of oil dis- 0charged from the cup at each downstroke of the spindle, and by makingthe oil-chamber larger or smaller the discharge of the oil from the cupmay be accurately regulated as the surfaces to be lubricated mayrequire.

The body of the oil-cup may be made of glass, metal, or'other suitablematerial, and of any desired size. On removing the cap Dthe oil may befilled into the cup or replenished at any time.

It is evident that the oil is discharged from the cup by the positiveaction of the spindle, which forms a plunger; hence the flow of oil fromthe cup will certainly follow the depression of the spindle, and the oilin the cup is 8:; always under cover; hence the oil fed to the bearingswill be free from dust and grit, and will have the best lubricatingeffect.

Whenever the spindle E is depressed, the stem f of the valve F willclear the oil-passage 0 b, to insure the discharge of the oil from thecup.

Having thus I claim as new, ters Patent, is-

1. An oil-cup comprising a body or oil-receiving vessel, A, providedwith a subjacent oil-chamber, G, an outlet, 1), and a valve-seat,

1), below said outlet, and a spring-pressed spindle, E, having a valve,F, at its lower end and ICC described my invention, what and desire tosecure by Letadapted to close the outlet b, and said spindle H, on thespindle, and said spindle having an 10 having a shoulder at e, forming aplunger to oil-ejecting shoulder at e,and avalve,F,adapteject the oilfrom the chamber G when the ed to close the outlet 12, substantially asherespindle is depressed substantially as herein in set forth. 5 setforth.

2. The combination, in an oil-cup, of the FRANKOSOAR SLANKER body orvessel A, having a screw-neck, B, and Witnesses: a removable cap, D, anoil-chamber, G, in the H. MoOoMAs, neck B, and an outlet, b,aspind1e,E,aspring, T. C. THOMAS.
